Tens of Vulnerabilities Patched by Apple in macOS and iOS. Apple this week started rolling out security updates for iOS, macOS, iPadOS, watchOS, tvOS, and Safari, to address tens of vulnerabilities, including some that could result in arbitrary code execution.
A total of 37 security holes were resolved with the release of iOS 14.7 and iPadOS 14.7, including a recently detailed bug that attackers could exploit to crash the Wi-Fi functionality of vulnerable devices.
According to security researchers with the ZecOps Mobile EDR Research team, the vulnerability could initially lead to remote code execution, but Apple silently included a patch to prevent code execution in iOS 14.4.
It could still be exploited to crash the Wi-Fi on devices running iOS 14.0 to iOS 14.6.
Other security bugs addressed with iOS 14.7 and iPadOS 14.7 could lead to arbitrary code execution, application termination, permission bypass, circumvention of sandbox restrictions, access to restricted data, denial-of-service, bypass of code signing checks or kernel memory mitigations, and information leaks.
MacOS Big Sur received patches for the highest number of vulnerabilities, namely 36.
